CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority from Japanese Patent Application No. JP 2006-105036 filed in the Japanese Patent Office on Apr. 6, 2006, the entire content of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a recording and reproduction apparatus and a method for recording and reproducing, for example, an information signal of a television broadcast program. [0004] 2. Description of the Related Art [0005] Recording and reproduction apparatuses for recording, for example, television broadcast programs on a recording medium, such as a hard disk or a digital versatile disc (DVD), and for reproducing a recorded television broadcast program have become popular. [0006] In such a recording and reproduction apparatus, when a user desires to cause a recorded television broadcast program or the like to be reproduced and views it, it is very convenient if reproduction candidate programs matching the user's preferences are recommended by the recording and reproduction apparatus. [0007] In Japanese Unexamined Patent Application Publication No. 2002-112186, a method for determining user's preferences on the basis of an electronic program guide (EPG) and viewing history information of the user and for displaying information on reproduction candidate programs to be viewed by the user is disclosed. SUMMARY OF THE INVENTION [0008] However, in the method disclosed in Japanese Unexamined Patent Application Publication No. 2002-112186, the user is informed of reproduction candidate programs determined on the basis of EPG information and viewing history information in units of programs. Consequently, there is a problem in that it is difficult to recommend and provide a program containing a specific scene matching the user's preferences. [0009] For example, when a certain user has a preference for cooking, in the method of the related art, it is possible to recommend and provide cooking programs. However, even if a so-called slot devoted to cooking (cooking slot; scene) exists in, for example, an entertainment program or a singing program, since the entertainment program in which the cooking slot exists is not listed as a cooking program, it does not become a recommended program. [0010] Furthermore, it is difficult to deal with a request from the user to extract only cooking slots and view them. [0011] In view of the above, it may be desirable to recommend to the user programs containing specific scenes preferred by the user and the specific scenes. [0012] According to a first embodiment of the present invention, there is provided a recording and reproduction apparatus which may include information signal recording means for recording an information signal on a recording medium; reproduction means for reading and reproducing the information signal recorded on the recording medium; feature amount detection means for detecting feature amounts of the information signal to be recorded and/or the reproduced information signal; division detection means for detecting divisions of the information signal by using the feature amounts detected by the feature amount detection means; keyword obtaining means for obtaining a keyword for each of a plurality of segmentation sections of the signal information, the keyword being associated with the segmentation section and each of the segmentation sections being specified by two adjacent divisions detected by the division detection means; keyword recording means for recording, for each segmentation section, the keywords obtained by the keyword obtaining means on the recording medium in such a manner as to correspond to each of the segmentation sections of the information signal; user operation input detection means for detecting operation input by a user; user evaluation value generation means for generating a user evaluation value on the basis of the operation input so as to correspond to each of the segmentation sections in such a manner that the operation input by the user is monitored by monitoring detection output of the user operation input detection means and a user evaluation value in a negative direction is assigned to operation input that does not request that the information signal be normally reproduced; keyword evaluation value accumulation and storage means for accumulating the user evaluation value for each of the keywords and storing the accumulated evaluation value for each of the keywords in such a way that the user evaluation value for each of the segmentation sections, generated by the user evaluation value generation means, is associated with the evaluation value of the keyword of the segmentation section; and recommendation means for referring to the evaluation values of the keywords stored in the keyword evaluation value accumulation and storage means in order to detect the information signal or the segmentation section having a keyword having a large evaluation value as the keyword of the segmentation section from within the information signals or the segmentation sections recorded on the recording medium, and for recommending the information signal or the segmentation section to the user. [0013] In the recording and reproduction apparatus according to the first embodiment of the present invention, when a user inputs an operation request such as one requesting a fast forward reproduction operation or skip instruction operation such that normal reproduction is not performed, a negative user evaluation value may be assigned to the segmentation section of the information signal at which the user may input an operation request requesting non-normal reproduction, and a more positive user evaluation value may be assigned to a preference section for which the user desires reproduction more. [0014] A user evaluation value for each of the segmentation sections may be accumulated for each of a plurality of keywords in such a manner that each of the user evaluation values corresponds to the evaluation value of the keyword at each segmentation section, and the accumulated user evaluation values for the keywords may be stored in the keyword evaluation value accumulation and storage means. Therefore, a keyword having a high user evaluation value among the keywords stored in the keyword evaluation value accumulation and storage means may be a keyword related to a scene preferred by the user. [0015] On the other hand, the information signal may be recorded together with the keyword for each segmentation section on a recording medium. The recommendation means may detect a segmentation section containing a keyword having a high user evaluation value related to a scene preferred by the user or an information signal containing the segmentation section from among the keywords stored in the keyword evaluation value accumulation and storage means, and may recommend it to the user. [0016] When a television broadcast program is taken as an example, the presented segmentation section may have a high possibility of being a scene preferred by the user. Furthermore, a program containing the segmentation section may have a high possibility of being a program containing a scene preferred by the user. Therefore, in the recording and reproduction apparatus according to a first embodiment of the present invention, a scene preferred by the user or a program containing a scene preferred by the user among the recorded information signals may be recommended to the user. [0017] According to a second embodiment of the present invention, there is provided a recording and reproduction apparatus which may include information signal recording means for receiving an information signal transmitted via a communication network and recording the information signal on a recording medium; reproduction means for reading and reproducing the information signal recorded on the recording medium; feature amount detection means for detecting feature amounts of the information signal to be recorded and/or the reproduced information signal; division detection means for detecting divisions of the information signal by using the feature amounts detected by the feature amount detection means; keyword obtaining means for obtaining a keyword for each of a plurality of segmentation sections of the signal information, the keyword being associated with the segmentation section and each of the segmentation sections being specified by two adjacent divisions detected by the division detection means; keyword recording means for recording, for each segmentation section, the keywords obtained by the keyword obtaining means on the recording medium in such a manner as to correspond to each of the segmentation sections of the information signal; user operation input detection means for detecting operation input by a user; user evaluation value generation means for generating a user evaluation value on the basis of the operation input so as to correspond to each of the segmentation sections in such a manner that the operation input by the user is monitored by monitoring detection output of the user operation input detection means and a user evaluation value in a negative direction is assigned to operation input that does not request that the information signal be normally reproduced; keyword evaluation value accumulation and storage means for accumulating the user evaluation value for each of the keywords and storing the accumulated evaluation value for each of the keywords in such a way that the user evaluation value for each of the segmentation sections, generated by the user evaluation value generation means, is associated with the evaluation value of the keyword of the segmentation section; scheduling information obtaining means for receiving transmission scheduling information containing information in the form of character information related to the information signal transmitted via the communication network; and recommendation means for detecting an information signal scheduled to be transmitted, the information signal containing a keyword having a large evaluation value among the evaluation values of the keywords stored in the keyword evaluation value accumulation and storage means, within the character information contained in the transmission scheduling information obtained by the scheduling information obtaining means, and for recommending the information signal to the user. [0018] In the recording and reproduction apparatus according to a second embodiment of the present invention, a keyword having a high user evaluation value among the keywords stored in the keyword evaluation value accumulation and storage means may be a keyword related to a scene preferred by the user, identical to the recording and reproduction apparatus according to the first embodiment of the present invention. [0019] In the recording and reproduction apparatus according to the second embodiment of the present invention, the recommendation means may detect an information signal scheduled to be transmitted, which contains a keyword having a high user evaluation value related to a scene preferred by the user from among the keywords stored in the keyword evaluation value accumulation and storage means, within character information contained in information contained in the information signal scheduled to be transmitted, such as EPG data, and may recommend the information signal scheduled to be transmitted. [0020] According to a second embodiment of the present invention, there is provided a recording and reproduction apparatus which may include information signal recording means for recording an information signal on a recording medium; reproduction means for reading and reproducing the information signal recorded on the recording medium; feature amount detection means for detecting feature amounts of the information signal to be recorded and/or the reproduced information signal; division detection means for detecting divisions of the information signal by using the feature amounts detected by the feature amount detection means; keyword obtaining means for obtaining a keyword for each of a plurality of segmentation sections of the signal information, the keyword being associated with the segmentation section and each of the segmentation sections being specified by two adjacent divisions detected by the division detection means; keyword recording means for recording, for each segmentation section, the keywords obtained by the keyword obtaining means on the recording medium in such a manner as to correspond to each of the segmentation sections of the information signal; user operation input detection means for detecting operation input by a user; user evaluation value generation means for generating a user evaluation value on the basis of the operation input so as to correspond to each of the segmentation sections in such a manner that the operation input by the user is monitored by monitoring detection output of the user operation input detection means and a user evaluation value in a negative direction is assigned to operation input that does not request that the information signal be normally reproduced; keyword evaluation value accumulation and storage means for accumulating the user evaluation value for each of the keywords and storing the accumulated evaluation value for each of the keywords in such a way that the user evaluation value for each of the segmentation sections, generated by the user evaluation value generation means, is associated with the evaluation value of the keyword of the segmentation section; reproduction control means for controlling a reproduction mode for the segmentation section or a reproduction mode of the information signal containing the segmentation section on the basis of the keyword for each of the segmentation sections recorded on the recording medium and the evaluation value of the keyword stored in the keyword evaluation value accumulation and storage means. [0021] Also, in the recording and reproduction apparatus according to a third embodiment of the present invention, a keyword having a high user evaluation value among the keywords stored in the keyword evaluation value accumulation and storage means may be a keyword related to a scene preferred by the user, identical to the recording and reproduction apparatus according to the first and second embodiments of the present invention.
